Default Same problem

I am having the same problem with my truck. I at least got the defroster to work-which is most important for winter. The black vacuum line coming through the firewall connects to the red vacuum tube coming from the controller. The dark brown wire i hooked to one of the black vacuum lines and i now get heat through the defroster and floor vent, but nothing from the dash vent. I would love to find out which vacuum color connects to which vacuum port on the plastic housing. I have not hooked up any of the other vacuum lines, but i have suction on 3 of the 5 remaining ports on the plastic connector. I have also tried various combinations-but the best i come up with is the two lines described above. The a/c works in the truck and i would like for it to come out the dash vents for the summer. Any info or pictures would be greatly appreciated. Jim.
